2. Validation of the single-platform ISHAGE protocol for enumeration of CD34+ hematopoietic stem cells in umbilical cord blood in a Brazilian center
Abstract Background This study aims to validate the single-platform method for enumeration of CD34+ cells, by comparing the performance of two different commercial kits, as well as to evaluate the efficiency of the AccuriTM C6 cytometer in providing direct counts of absolute cell numbers. Method We evaluated 20 samples from umbilical cord blood (UCB), comp

3. USE OF PUPILLOMETRY IN THE DIAGNOSIS OF STRESS IN PIGLETS TRANSPORTED IN A TROPICAL CLIMATE
ABSTRACT The objective of this study was to evaluate the reactivity of the pupillary area (PA) as a non-invasive method for diagnosing stress in piglets submitted to transport. A total of 10 journeys were monitored and grouped according to the transport distance (15 and 75 km). Were sampled 360 piglets (25±3.8 kg) to measure the PA, body temperature (BT), a

4. A Systematic Pipeline to Enhance the Fecal Metabolome Coverage by LC-HRMS
The comprehended knowledge of the metabolic profile of the fecal matter has been recognized as an important point for understanding metabolic changes in the human systemic metabolism and it can provide precious information about host-gut microbiota interactions. However, few analytical strategies have been addressed for a broad analysis of metabolites with d

5. USO DE UM SCANNER DE MESA E ESPUMA DE POLIURETANO PARA QUANTIFICAÇÃO DE FERRO TOTAL EM CÁPSULAS DE SUPLEMENTOS ALIMENTARES
In this work, an alternative and low-cost technique for the extraction and quantification of Fe (total) from food supplements by digital image analysis is shown. The method is based on the complexation of Fe ions in solution with the 8-hydroxyquinoline ligand, forming a colored complex that is extractable from aqueous solution to polyurethane foam, coloring

6. RAPID DETECTION OF VITAMIN C CONTENT IN FRUITS AND VEGETABLES USING A DIGITAL CAMERA AND COLOR REACTION
In this study, we propose a novel method to determine the vitamin C content in fruits and vegetables. The proposed method exploits the image and data processing abilities of computers by coupling a digital camera and a color reaction. An image acquisition device was developed to collect the image information of the solution to be measured after the color rea

7. Was „eine Mädchen”, „eins Mädchen” und „Ø Mädchen” gemein haben: Zur Relevanz sprachtypologischer Korrelationen beim Transfer in die L2 Deutsch aus typologisch unterschiedlichen Sprachen
Abstract Whether for exchanging interpersonal needs -such as thoughts- or for business purposes -as in the case of the Lingua franca- in its specific form language has always been presumed to be the human species’ means for communication. With the concurrent rise in demand for multilingualism in the 20th century, studies examining language acquisition have

8. A estrutura silábica do alemão como língua estrangeira na interlíngua de aprendizes brasileiros
Resumo A presente pesquisa explora as estratégias de reformulação de constituintes silábicos complexos na Interlíngua de 18 brasileiros aprendizes do Alemão como Língua Estrangeira. Nossa hipótese prevê que estes aprendizes possuem dificuldades na produção de ataques iniciais e codas finais do ALE e, ao tentar acomodá-las ao molde silábico da LM

9. On syllable structure and phonological variation: The case of i-epenthesis by Brazilian Portuguese learners of English
Abstract Our study employs nonword-learning tasks to examine i-epenthesis in the speech output of 53 Brazilian Portuguese learners of English. One aim is to investigate conflicting views on the syllabification of consonants in various word-medial and final contexts, where they can be parsed as either codas or onsets of empty nuclei. Another aim is to test a

10. Feeding behavior by hummingbirds (Aves: Trochilidae) in artificial food patches in an Atlantic Forest remnant in southeastern Brazil
ABSTRACT During flight, hummingbirds achieve the maximum aerobic metabolism rates within vertebrates. To meet such demands, these birds have to take in as much energy as possible, using strategies such as selecting the best food resources and adopting behaviors that allow the greatest energy gains. We tested whether hummingbirds choose sources that have high

11. QUALITY OF A DIGITAL TERRAIN MODEL FOR SANTA CATARINA STATE
ABSTRACT: Relief characterization using a digital terrain model (DTM) is widely applied in erosion, soil and vegetation modeling. However, factors, such as acquisition technology and the spatial resolution of the digital model, affect modeling results. The aim of this study was to characterize noises in a DTM of the entire state of Santa Catarina recently ma

12. Evaluation of the antiplasmodial and leishmanicidal potential of Myrciaria dubia (Myrtaceae) extract
Abstract INTRODUCTION: Malaria and leishmaniasis are prevalent in tropical regions, which have environmental characteristics that are highly favorable to protozoa and vectors of these diseases; the transmission of these infections in sub-tropical regions, although recognized, represents only a small fraction of cases. Plants are constantly being used in the
